embedding additional information into jxf-files?

hello,
i write live input to jfx file sequences and i would like to save some additional information along with them…. how would i do that?
currently i write 1 plane @1920×1080. into these jxf-file i’d like to embed a smaller depth map (640×360) plus a single boolean variable (0/1).
i guess i could make my one plane bigger and splice it up with math operators but i wonder wether there might be a more elegant solution?
and… if it is splicing up single planes, what objects should i be looking at?
as always, thanks a lot for help!!!

i figured it out, sorry for making a stir – i did not know there are readymade commands for this…
if someone else should be as ignorant as me: jit.concat, jit.scissors and jit.glue is the way, jitter tutorial 13 shows where to go.
